Ruby Requires Chilkat v11.0.0+

Workaround for the deprecated Crypt2.OpaqueVerifyString method

Shows how to replace the deprecated OpaqueVerifyString method. (Chilkat is moving away from the use of CkByteData.) Ruby

require 'chilkat'

success = false

crypt = Chilkat::CkCrypt2.new()

#  Specifies how the original data bytes are converted to characters
crypt.put_Charset("utf-8")

path = "c:/someDir/example.dat"

#  ------------------------------------------------------------------------
#  The OpaqueVerifyString method is deprecated:

inData = Chilkat::CkByteData.new()
inData.loadFile(path)

originalText = crypt.opaqueVerifyString(inData)

#  ------------------------------------------------------------------------
#  Workaround.
#  (Chilkat is moving away from using CkByteData)

bd = Chilkat::CkBinData.new()
bd.LoadFile(path)

#  If the opaque signature is validated, the contents of bd are replaced with the original data that was signed.
success = crypt.OpaqueVerifyBd(bd)

#  Indicate how the bytes are converted to chars by passing the charset.
originalText = bd.getString("utf-8")
